GLuint  programHandle 
)
static

Get the the binary data of a program from the microcode cache.

◆ writeMicrocodeToCache()

static void Ogre::GLSLProgram::writeMicrocodeToCache ( uint32  id,
GLuint  programHandle 
)
static

add the microcode to the cache

◆ updateAtomicCounters()

◆ extractLayoutQualifiers()

void Ogre::GLSLProgramCommon::extractLayoutQualifiers ( void  )
inherited

◆ getGLProgramHandle()

uint Ogre::GLSLProgramCommon::getGLProgramHandle ( void  ) const
inlineinherited

Get the GL Handle for the program object.

◆ activate()

virtual void Ogre::GLSLProgramCommon::activate ( void  )
pure virtualinherited

Makes a program object active by making sure it is linked and then putting it in use.

Implemented in Ogre::GLSLSeparableProgram, Ogre::GLSL::GLSLLinkProgram, Ogre::GLSLESProgramPipeline, Ogre::GLSLESLinkProgram, and Ogre::GLSLMonolithicProgram.

◆ isUsingShader()

bool Ogre::GLSLProgramCommon::isUsingShader ( GLSLShaderCommon shader) const
inlineinherited

query if the program is using the given shader

References Ogre::GpuProgram::getType().

◆ updateUniforms()

virtual void Ogre::GLSLProgramCommon::updateUniforms ( GpuProgramParametersPtr  params,
uint16  mask,
GpuProgramType  fromProgType 
)
pure virtualinherited

Updates program object uniforms using data from GpuProgramParameters.

Normally called by GLSLShader::bindParameters() just before rendering occurs.

Implemented in Ogre::GLSLSeparableProgram, Ogre::GLSL::GLSLLinkProgram, Ogre::GLSLMonolithicProgram, Ogre::GLSLESLinkProgram, and Ogre::GLSLESProgramPipeline.

◆ getFixedAttributeIndex()

static int32 Ogre::GLSLProgramCommon::getFixedAttributeIndex ( VertexElementSemantic  semantic,
uint  index 
)
staticinherited

Get the fixed attribute bindings normally used by GL for a semantic.

◆ useTightAttributeLayout()

static void Ogre::GLSLProgramCommon::useTightAttributeLayout ( )
staticinherited

use alternate vertex attribute layout using only 8 vertex attributes

For "Vivante GC1000" and "VideoCore IV" (notably in Raspberry Pi) on GLES2
